301 : Requested resource has been definitively moved to the URL given by the Location headers.
400 : The server cannot or will not process the request due to something that is perceived to be a client error.
206 : Request has succeeded and the body contains the requested ranges of data, as described in the Range header of the request.
404 : Page Not Found.
302 : Resource requested has been temporarily moved to the URL given by the Location header.
405 : The server knows the request method, but the target resource doesn't support this method.
204 : It indicates that a request has succeeded, but that the client doesn't need to navigate away from its current page.
304 : Indicates that there is no need to retransmit the requested resources.
500 : The server encountered an unexpected condition that prevented it from fulfilling the request.
What is Method?
Web clients and servers communicate by using a request/response protocol called HTTP, which is an acronym for Hypertext Transfer Protocol. HTTP includes two methods for retrieving and manipulating data:
GET
Retrieves data from the server. The target of the request (referred to as a resource) is specified as a URI (Uniform Resource Identifier). This is usually (but not always) an absolute reference to a file on the server and is referred to as a URL (Uniform Resource Locator) when used in this context. Additional parameters, called Query Parameters, can also be specified.
POST
Posts data back to the server. In addition to a URL and query parameters, a POST request includes a payload. The payload is usually form data, the aggregated contents of the various fields (also called controls) that were in the response.
What is Protocol?
A web server is software and hardware that uses HTTP (Hypertext Transfer Protocol) and other protocols to respond to client requests made over the World Wide Web.
HTTP 1.0
HTTP 1.0 introduces a number of new features, including the ability to connect to multiple servers at the same time, support for persistent connections, and support for the POST method.
HTTP 1.1
HTTP 1.1 is the latest version of Hypertext Transfer Protocol (HTTP), the World Wide Web application protocol that runs on top of the Internet's TCP/IP suite of protocols. HTTP 1.1 provides faster delivery of Web pages than the original HTTP and reduces Web traffic.
What is Endpoint?
A web service endpoint is an entity, processor, or resource that can be referenced and to which web services messages can be addressed. Endpoint references convey the information needed to address a web service endpoint. Clients need to know this information before they can access a service.
What is Content Size?
The Content size/Content-Length header indicates the size of the message body, in bytes, sent to the recipient.
What is Anomaly/Anomaly Detection?
Anomaly is data points in data that don't fit the normal patterns.
Anomaly detection is the process of finding outliers in a given dataset. Outliers are the data objects that stand out amongst other objects in the dataset and do not conform to the normal behavior in a dataset.
